Question

我正在构建一个与nodemcu连接的应用。在我的代码中，我使用的是HttpClient，但正如我所读到的那样，它已不再受支持了。我想在下面的代码中使用httpurlConnection。如果使用httpurlconnection，我会收到错误。这是代码

if (!dialog.isShowing())
        dialog.show();

        String val = params[0];
        final String url = "http://" + serverAdress + "/led/" + val;

        try {
            HttpClient client = new DefaultHttpClient();
            HttpGet getRequest = new HttpGet();
            getRequest.setURI(new URI(url));
            HttpResponse response = client.execute(getRequest);

            InputStream inputStream = null;
            inputStream = response.getEntity().getContent();
            BufferedReader bufferedReader =
                    new BufferedReader(new InputStreamReader(inputStream));

            serverResponse = bufferedReader.readLine();
            inputStream.close();

        } catch (URISyntaxException e) {
            e.printStackTrace();
            serverResponse = e.getMessage();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
            serverResponse = e.getMessage();
        } catch (IOException e) {
            e.printStackTrace();
            serverResponse = e.getMessage();
        }

        return serverResponse;
}

Answer 1

我建议你看一下OkHttp图书馆。实际上，最新版本的HttpsURLConnection使用OkHttp引擎盖。或更高级别的库Retrofit，它使用OkHttp但其API更易于使用。此外，如果您的服务器是RESTful，您可以使用适配器/转换器简单地反序列化对Java对象的响应。

试试这个：

HttpsURLConnection request = (HttpsURLConnection) (url.openConnection());
request.setRequestMethod("GET");
request.connect();
String result = readStream(request.getInputStream());
request.disconnect();

Httpclient替代方案
